Lyuben Todorov commented on CASSANDRA-6157:
-------------------------------------------

Ah, I see what you mean with regards to point *1*, as for renaming the function it it is an override but PerDC just feels like it's more specific as we are configuring the hinted handoff for each datacenter.

> Cassandra supports disabling the hints or reducing the window for hints. 
> It would be helpful to have a switch which stops hints to a down data center but continue hints to other DCs.
> This is helpful during data center fail over as hints will put more unnecessary pressure on the DC taking double traffic. Also since now Cassandra is under reduced reduncany, we don't want to disable hints within the DC.
